The collective intelligence of humans is remarkable. We all share 99% of genes, yet when you look at the vast majority of the population at any given instant, the amount of ignorance and differing knowledge is stunning. Look at the achievements of humans. But, given a single individual who is deemed to be the “most intelligent” of the population, you will not find in him the majority of which is required to construct and maintain of the structures humans have built.  The smartest one will only be an expert in a specific field of knowledge. Their contributions include discovering the Theory of Relativity, proving the incompleteness of logical systems (Godel’s Theorem) or writing rules for Calculus and other such concepts we now have in our library of knowledge.
This reliance on the collective is very interesting; especially considering the United States is built upon  the concept of individual freedom. So, I suggest you compare the collective societies, where the individual has his freedom secondary to the state. In these populations, you don’t have the same level of massive collective intelligence as in Capitalist societies. Instead, these societies tend to have a population which share a single monotonous intelligence. It seems paradoxical to have such a collective strength emerge out of a multitude of distinct autonomous units and a lack of such strength when these units are more uniform in their actions. But is it precisely this power of individual freedom and expression which leads to the formation of reliance on collective interactions.
